Romulus was the adopted homeworld of the Romulans and capital planet of the Romulan Star Empire. The planet was also known as ch'Rihan (lit. "of the Declared" in the Romulan language) and 128 Trianguli III-A (in the astronomical notation of Earth). In yet another language, the planet was known as Rom'laas, and in another catalog system, Ket-cheleb III. Romulus was the third of ten planets, and its tidally-locked "sister world" was known as Remus. Together, Romulans and Remus were sometimes called the Hearthworlds. Remus and the planet Romulus had a "Trojan relationship" in the way they revolved around each other. The sun around which Romulus orbited was known as Eisn.

The planet was noted as being rich in different kinds of organic life with a climate far better then what was present on Vulcan with abundant supplies of water with much larger seas. Varying types of habitations were also present from deserts to volcanic regions with firefalls. Though it was rich in organic life, its metal content was somewhat rarer with much of it being present deep within the planet, which was a contrast to the world's sister planet.

As such, it was seen as a resource poor world compared to its sister planet with Romulus lacking fossil fuels, hard metals and radioactives. (FASA RPGmodule: The Romulans)

Historians believe that Romulus and its sister world of Remus were in fact once a single large planetoid known as Romii. The biggest change that geologists have determined to have to Romii was five-point three billion years ago when another planetary body, which was at least sixty percent the size of Romii and in retrograde orbit, collided with the large planet. The impact stripped the outer crust from Romii and, in less then two hundred years, the ejecta had coalesced into a single body that would eventually cool to become the planet known as Romulus which would continue to spin with the force of that ancient catastrophic collision.

Romulus was completely destroyed when the Hobusstar went nova in 2387. Prior to the destruction, Spock attempted to warn the Romulan Senate that the supernova posed a threat to both the planet and the entire Romulan Star Empire, but was rebuffed. However, a few weeks later, the Romulan Senate observed that the Hobus star was increasing in mass and was growing more unstable which led to them concluding that Spock was correct. A scientist predicted that it would take a few weeks at most for the shockwave to reach Romulus once the star went nova. PraetorChulan proclaimed he would put the matter up for vote in the Senate, then gave the order to begin evacuation protocols for Romulus.
